GUL'I'IVATOB ATTACHMENT.

Specification of Letters Patent.

Patented May 10, 1910.

Application filed June 11, 1909. Serial No. 501,615.

To all whom it may concern:

Be it known that I, CONRAD SELL, a citizen of the United States,residing at Arcadia, in the county of Valley and State of Nebraska, haveinvented certain new and useful Improvements in Cultivator Attachments;and I do hereby declare the followmg to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to new and useful improvements in attachments forcultivators and my object is to provide means for guiding the cultivatorframe independently of the draft animals and a further object is toprovide means for simultaneously shifting the parts carrying thecultivator shovels and shanks to retain the same in proper relationshipwith the row.

Other objects and advantages will be hereinafter referred to and moreparticu' larly pointed out in the claims.

In the accompanying drawings forming part of this application, Figure 1is a perspective view of a portion of the cultivator frame showing myimproved attachments applied thereto, and, Fig. 2 is an elevation of aportion of the frame and operating parts.

Referring to the drawings in which similar reference numerals designatecorresponding parts throughout the several views, 1 indicates the frameof a wheeled cultivator, to the depending portions 2 of which aresecured standards 3, there being a standard at each edge of the frame,said standards being rotatably mounted in sockets 4t which are securedin any preferred manner to the depending portions 2. The lower ends ofthe standards 3 are extended at right angles to form spindles 5, uponwhich are to be mounted the usual or any preferred form of supportingwheels 6, said wheels being secured on the spindles in any preferredmanner, as by means of nuts 7, which engage the threaded stems 8 at theouter or free ends of the spindles and in order to limit the verticalmovement of the standards 3, said standards are provided with collars 9,which are adapted to engage the lower edge of the lowermost socket 1 andbear thereagainst, the object in rotatably mounting the standards 3being to permit the wheels to be swung inwardly or outwardly to guidethe frame 1 independently of the draft animals. To readily accomplishthis result, the upper ends of the standards 3 are provided with levers10, which are fixed to the standards in an suitable manner and areconnected at their outer ends by means of a bar 11 and it will bereadily seen that by moving said bar lengthwise, one of the wheels willbe moved inwardly at its forward edge and the opposite wheel outwardlyat its forward edge, thereby quickly shifting or moving the frame of thecultivator laterally as said cultivator is moved forwardly.

At the longitudinal center of the bar 11 and preferably on the underface thereof is provided a toothed rack 12, with which is adapted tocooperate a pinion 13 carried by a shaft 14-, said shaft being mountedin suitable bearings 15 and it will be readily seen that by grasping thehand wheel 16 at the outer end of the shaft 14 and rotating the shaft 11, the bar 11 will be shifted longitudinally to properly position thewheels to guide the cultivator.

The cultivator shovels 17 are attached to the usual form of shanks 18,the forward ends of said shanks being in turn attached to the lower endsof the yoke 19, said yoke being movably attached to parts of thecultivator frame, whereby said yoke may be moved laterally to retain theshovels in alinement with the row of plants being cultivated and inorder to simultaneously operate the yoke with the turning of the wheels,the horizontal portion 20 of the yoke 19 is provided with a toothed rack21, which is adapted to cooperate with a pinion 22 on the shaft 14 andby placing the pinion above the horizontal portion 20, the yoke will bemoved in opposition to the bar 11, that is to say, when the shaft 1 1 isturned to the left, the bar 11 will be moved longitudinally to the left,while the yoke 19 will be moved bodily to the right and by this doubleadjustment, it will be readily seen that the cultivator shovels may bereadily kept in alinement with the row, even though the draft animalsmove out of direct alinement with the row.

In operation, supposing the draft animals move out of direct alinementwith the row, or to the left thereof, whereby the shovels at the rightside of the cultivator will be drawn into close proximity to the row,the shaft 14 is to be rotated to the left, which will result in turningthe wheels to move the frame of the cultivator laterally or toward theright,

while the yoke 19 will be simultaneously moved to the right, therebymaintaining the shovels in proper alinement with the row until such timeas the draft animals can be brought into proper alinement with the row,when the shaft 14 is operated to bring the wheels to the proper courseand move the yoke to the proper position on the cultivator frame.

It will be readily understood that this form of device can be verycheaply constructed and at the same time made strong and durable and byproperly manipulating the shaft, the turning operation at the ends ofthe rows may be more readily accomplished.

What I claim is:

1. A cultivator attachment comprising a frame, a movable yoke, said yokehaving a rack upon its upper surface, about centrally thereof, standardsof right angled outline having their vertical portions pivoted laterallyto said frame and adapted to swing horizontally, said standards havingtheir horizontal arms provided with spindles, a rotatable shaft arrangedcentrally of said frame and journaled thereon, levers con- -nected tothe upper end of said standards and a connecting bar having pivotalconnection with said levers, said connecting bar being provided with anoutwardly facing rack, said shaft having pinions, one of said pinionsengaging the downwardly facing rack of said connecting bar and the otherpinion engaging the upwardly facing rack of said yoke, and means formanually actuating said shaft.

2. In a cultivator attachment, the combination with a frame, an invertedU shaped yoke having a toothed rack on the upper face of the uppercentral portion thereof and shanks with cultivator shovels thereonmounted on the lower portion of said yoke; of standards pivotallymounted on the vertical portion of said frame and having their lowerportions bent at right angles to form spindles, a bar having a rack onthe under face of its central portion, levers pivotally connecting saidbar and the upper portions of said standards, a shaft mounted centrallyon said frame carrying a pair of pinions, one engaging the upwardlyfacing rack on said yoke, the other engaging the downwardly facing rackon said bar and means to rotate said shaft, whereby when the wheels ofsaid cultivator are turned in one direction, the yoke willsimultaneously move in the opposite direction, thereby maintaining theshovels in proper alinement with the rows.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

CONRAD SELL.
